Well I'm glad someone agrees 
Another thing that makes you wonder is that the 22RE with 10 years of evolution (including an extra 400cc and fuel injection) is rated at 87kW... 2kW less than the more pedestrian 18RC!

I have the old road tests of the 18R-C in the RA23/28 and 40 series and it is definately 87 to 89 bhp - not kilowatts, at the flywheel.
Meaning 66kw there - big whoop.
Subtract one for every year you have owned the car since it was brand new and my RA23 18R-C had 38kw by the time I reefed that boat anchor out

Just drop in an 18RG, there are a few on the for sale forums at the moment. Sure it won't be a super quick car but it will be a bit of fun to play with! Its especially good when on limited funds.

Hi,
| V8_MA61 wrote on Thu, 26 August 2004 23:52 |
yes i think that is 89hp...
18rg only had like 120 or something didnt it?
|
The initial 18RG had 145bhp, later versions had less power due to lower compression and pollution controls.
I don't think the final EFI, with larger-valve head version of the 18RG could muster the same power as the early carbie version. I think it topped out at around 130bhp.

i had my worked 18R-C in my RA28 flogging 18R-G's, depending on what year model it came in, they go from 95-102 varying sources..
the mods done to my 18R were custom grind cam from tighe engeneering, twin side-drafts off an 18R-G on 2 custom manifolds, custom extractors, and just a 2" sports system..and it beat the pants off 18R-G's, it revved harder too! once the cam cam into it's range holy shit! (it was a big cam) but, as one could imagine, the dated 77' engine had it's days, and after much 8000+ rpm flogging (awsome induction note) a head gasket went, and drop in hp was noticable, when i sold the car i put all the stock stuff back in/on, it is still going as far as i know, with a new gasket ofcourse!
there a tough motor!
if anyone is interested in the custom manifolds PM me, i still have them, minus carbies..

dont forget the 22r with its 10years of evolution became a motor with shit loads of torque. not much more power but its all down low. big stroke 4 cylinder.

You will find that I already covered this in my first post. My engine was *very* healthy and made 86rwhp (or something in that vicinity - maybe 84hp?).
The car (auto Mark II) ran 18.6 down the quarter, so I'd suggest that and MS85 Crown would be lucky to better a low 19.

The 18R-C definetly has 66kW. They, like the 21R-C which is rated at 67kW couldn't pull the skin off a banana. There is NO way they make 80-anything kilowatts.

I don't understand that. The lowest powered 18RG had about 120-125hp, which is still more than your worked 18RC.
Maybe the 18RG's you raced against were poorly tuned, 'cos in the real world, a healthy 18RG would tramp all over an 18RC, given all other things (car, tyres, weight, etc) being equal.

97hp-102hp stcok for an 18r-c, 18r-g's go from 130-145hp..my worked 18r-c pulled freely to 8000rpm and had around 150-160hp (est) don't underestimate thier potential, they just need to breath better and they rev like a twin cam..there are after all the same bore/stroke, so there and oversquare engine..(i should also note, it was never properly tuned! no body wanted to attempt it!)

Getting 150 to 160 bhp from an 18R-C is easily do-able with a bigger single carby, the right profile cam shaft and extractors. It was been done for a while when this combo was used in RA40's modified to rally in Austraila. You will always beat a std 18RG if you have gone to this trouble with your 18R-C, but it begs the question as to why would you want too ????? Start with an 18RG in the first place, it hasa minimum of 30 more bhp in std form before you start to play with it .......and away you go from there.
Cheers,
Mitch.

do you know how hard it is to come across an 18R-G in good condition? complete...my old man has a fully rebuilt one in his RA40, i wanted to beat that with my non cross-flow single cam piece of shit..he he he it worked very well..everyone thought it was a twin cam anyway..
